STEMCELL Technologies GloCell™ Fixable Viability Dye Violet 510, Size: 500 Tests
GloCell™ Fixable Viability Dye Violet 510 is a fluorescent cell viability dye for staining live/dead mammalian cells in applications such as flow cytometry. The dye irreversibly binds intracellular and cell surface amine groups and can be utilized prior to fixation, permeabilization, or cryopreservation. Cells with compromised plasma membranes become permeable to the GloCell™ dye, resulting in a greater fluorescence compared to live cells in a cell viability assay.GloCell™ Fixable Viability Dye Violet 510 is excited by the violet laser at 405 nm and it has a fluorescence emission maximum of 510 nm that can be detected using the 525/50 band pass filter used to detect AmCyan.

Medchemexpress LLC Desthiobiotin-NHS ester | 80750-24-9 | MFCD08062086 | 98.0% | 311.33 g/mol | C14H21N3O5 | 100 MG
Desthiobiotin-NHS ester is a desthiobiotin analog bearing an N-hydroxysuccinimide (NHS) ester that selectively reacts with primary amines to form stable amide bonds. The desthiobiotin moiety binds streptavidin with lower affinity than biotin, allowing reversible affinity capture and mild elution, making it useful for labeling, enrichment, and probe development in biochemical assays.
- Selective labeling of primary amines.
- Enables reversible streptavidin-based affinity capture.
- Forms stable amide bonds for durable conjugation.
- Suitable for protein labeling and pull-down assays.
- Available in multiple package sizes for research scalability.
Enzo Life Sciences TSQ (ultra pure), (25mg), CAS Number: 109628-27-5
Zinc dye . TSQ is an efficient membrane-permeable fluorescent probe for zinc (II). It is selective for Zn (II) in the presence of physiological concentrations of Ca (II) and Mg (II) ions. Fluorescence of TSQ is enhanced upon binding Zn (II), but the probe does not demonstrate a shift or change in emission wavelength. TSQ forms a largely insoluble 2:1 (Ligand-Metal) complex with zinc and emits blue light upon excitation at 365 nanometers. Alternative Name: N-(6-Methoxy-8-quinolyl)-p-toluenesulfonamide. Formula: C17H16N2O3S. MW: 328.4. CAS Number: 109628-27-5. Purity: ≥98% (HPLC). Solubility: Soluble in DMSO. Use/Stability: Stable for at least one year after receipt when stored as recommended. Long Term Storage: -20°C
